But further analysis is necessary to make sure whether the vertical or the horizontal prompting is the main reason for the damage . the structure model experiment has been done by the researchers of the earthquake engineering research division , dalian university of technology . the model is scientifically simulated according to the similitude rule 作者通过震害分析以及一个简单的例子说明，单从宏观震害现象还不足以断言地震动的水平还是竖向振动分量是烟囱破坏的主要原因，还必须利用其他数据知识作进一步的分析。
According to the computation , there is much difference among the calculations with different methods . so the scientific computation theory of the seismic response of structure is still pre - mature . this paper does a lot work for the improvement of the computation theory , and it will be more perfect with more attention paid in the future 但竖向振动的作用不可忽视，尤其对烟囱上部的破坏起重要作用最后通过实验结果与计算结果的比较，作者发现各种计算方法的结果之间存在着较大的差异，这说明目前关于烟囱竖向地震力的计算理论仍然处于探索阶段，尚很不完善，需要今后更加深入和精确的研究。
Through the dynamic character analysis of the large annular cantilever beam string stadium roof structure , it was obtained that the stiffness of the structure was between the stiff structure and flexible structure and the frequencies were dense , vertical vibration was dominant and then the string beam ' s lateral vibration and torsion vibration 通过对大型环状悬臂型张弦梁挑蓬结构动力特性分析表明，该结构的刚度介于刚性结构与柔性结构之间，频谱比较密集，以竖向振动为主，同时伴有张弦梁侧向振动和扭转振动。
